Helen, I want to give my babies the best I can. I have some water sprite I can put in the tank to give some cover. I have fine gravel and sand I could put on the bottom of the tank. I had it bare to make it easier to siphon debris from the bottom when I do water changes. I turn the filter off make when I feed baby brine shrimp so that it doesn't circulate all over. It might be a scary tank, it sits at one end of the kitchen counter (which is busy). Describe a generic apisto raising out tank for me. How are yours set up? > Daniel, > I cannot see any reason for you to turn off the filtration. Apart from > loosing the bacteria the flow from the filter circulates the heat in your > tank.
